Application Scope

The characteristics and limitations of the buses, which are widely used nowadays, are analyzed in this paper. Because these buses don’t adapt to the high-reliability embedded computer system, a novel bus is proposed which is characterized by its high-reliability. And its capacity is reached through its unique datum’s dynamic reconfiguration mechanism. The basic architecture and communication protocol are presented in this paper. And then the key points during realization of this bus are discussed. Finally, the probably application scope and prospects are indicated.

The Boundary Element Method (BEM) has seen increasing use in the space industry to predict vibroacoustic responses of spacecraft and launch vehicle structures. The BEM application is used in the low-frequency regime where Statistical Energy Analysis (SEA) is usually inapplicable. This paper documents a vibroacoustic study of the Delta II 10-ft composite fairing using BEM and SEA. The fairing vibration and internal acoustic levels are predicted. The BEM and SEA predictions are compared with data from the Delta II 10-ft composite fairing acoustic test. The relative accuracy of the BEM and SEA methods in various frequency ranges is discussed. In addition, computer system requirements and lessons learned from BEM and SEA modeling are presented.

Train-Ground communication system is mainly used to complete the communication between the train and the ground, the data which is produced by security computer system is vital to safe operation. The paper focus on the reliability and security technologies of embedded computer system and evaluates the reliability of TMR (Triple Modular Redundancy), which is based on the existing research of security computer and aimed on the equipment of CBTC Train-Ground communication system. The technology of CBTC Train-Ground communication is studied and the structure of the TMR for Train-Ground communication system is designed in the paper. Furthermore, the fault - safety circuits，electromagnetic compatibility technology and rail traffic-related safety standards are analyzed. Finally, the Train-Ground infrared communication security transponder system based TMR is applied to Shanghai People's Square Line 8 subway train’s double-door control system.
